Select a Voice with the numeric keypad
Using the numeric keypad is the quickest way to go directly to
the Voice you need, but you must know the exact number of the
voice. The name and corresponding number of all the Voices in
memory are silkscreened above the display on the right. Youll
see that they start from number 01 through to number 147.
Two-digit voice numbers are selected by entering the two
digits in sequence.
For example, to select Voice number 17 (Organ 1), press
button [1] then button [7].
Three digit voice numbers are entered by first pressing the
[VOICE]/[+100] button to specify the hundreds, then
pressing the remaining two digits in sequence.
Dual voice (play two layered voices)
To play with the DUAL option (with two layered sounds), press the
[DUAL] button. The message VOICE 2 appears in the display
as well as the voice number assigned to the layered section.
If you play on the keyboard, you will hear two sounds for
every note played. In our example, you will hear the Piano
voice (01) together with Strings (49).
In DUAL mode, whatever voice selection you make will always
be assigned to the second voice.
To return to NORMAL single voice play, press the [DUAL] button again.
Keyboard percussion
To play percussive instruments on the keyboard, select the
DrumKit from the DRUMKIT group. The DrumKit is recalled
using exactly the same method used to recall a Voice; by
inserting the corresponding number on the numeric keypad
when the instrument is in NORMAL mode (not DUAL or SPLIT).
To recall the STANDARD Drum Kit, simply input voice number
129.
1. Press the [VOICE]/[+100] button to select the hundreds.
2. Insert the two remaining digits; 2 then 9.
With the DRUMKIT selected, the keyboard transform into a device
which plays all the percussive sounds of a real drum kit. You can
see what kind of percussive instrument each note plays by referring
to the silkscreened markings on the rail under the keyboard.
To return to normal playing, simply recall a Voice from any
group except the Drum Kit group.
Note: To play all the sounds of a Drum Kit, it is important
to remember that the keyboard must not be in Split or Dual
mode. Be sure, therefore, that the left display arrow is
pointing to the NORMAL function.

(Fa#3)
Split keyboard
To play on a split keyboard with one or two voices on the
right hand side (UPPER keyboard) and one voice on the left
(LOWER keyboard), press the [MODE] button as many times
as necessary until the left display arrowhead points to the
SPLIT function.
The keyboard will be split into a Lower section and an Upper
section. If you play on the keyboard, you will hear one sound
(01:Piano 1) on the right hand side of the keyboard and
another sound (49: Strings) on the left.
You can check the sound assigned to the lower section .
Play in Split mode with a Dual option on the Upper keyboard
To play with two layered sounds on the Upper keyboard and
one on the Lower, simply press the [DUAL] button while you
are in SPLIT mode.
If you want to change the voices on the Upper keyboard,
proceed as already described on the previous pages for Single
and Dual voice selection.
To change the Voice of the Lower section, hold down the
[MODE] button and proceed as already described to change
the voice number.
To cancel Split mode
To escape Split mode and return to a full NORMAL keyboard,
press the [MODE] button once.
The MEMORY
So far, you have learnt how to select single and combined
Voices in Normal, Dual and Split modes using a number of
panel operations. If, every time you want to create a preferred
sound combination, you have to take several steps to arrive
at your goal, you would ask yourself if there wasnt a quicker
way of selecting what you want. The answer lies in the
MEMORYwhich offers a quick and simple method of recall-
ing a panel situation at the touch of a single button.
A MEMORYis simply a combination of voices and other panel
settings (Voices, Track Volumes, Effect type and level, Style,
Variation, Chord Recognition mode, Split Point, etc.). The
GK340 contains six Memory which recall factory-set panel
configurations, but you can also memorize your own
combinations using the STORE MEMORYfeature.
Selecting the Memory
1. Take a quick look at the display, then press one of MEMORY
buttons (M1 - M6); for example, press the [M1] button.
The display shows the situation recalled by the MEMORY .
If you were playing in NORMAL mode, after selecting the
Performance you will find that the keyboard will be split
and the mode will have changed to either Fingered, or
One Finger, to enable the Styles. You will also see a change
of Style number. For more information about how to recall
Styles by selecting the MEMORY, refer to the section entitled
The Styles on page 9).
2. Repeat the selections for all the other Performance buttons,
observe the changes in the display and play on the
keyboard to listen to the change of voices.

DECREASE VOLUME
INCREASE VOLUME
Balancing the Lower and Upper sections
If you are playing in Normal mode with Voices on a Split
keyboard, you may at some stage want to adjust the volume
of one section with respect to the other. Using the
[MIXER]
Volume controls, you will be able to balance your Upper and
Lower voices to the levels required very easily.
The MIXER consists of 5 twin buttons organized in two rows.
The top row of buttons are [INCREASE VOLUME] controls
while the bottom row are [DECREASE VOLUME]
controls. When you are playing with voices only, voice
balancing tasks require the use of the [UPPER] and
[LOWER] controls only. The other three controls,
(Drums, Bass and Accomp), are explained under Styles on
page 12.
To increase the volume of, the Upper section, for example,
press the top [INCREASE VOLUME] button and hold it down
until you reach the Volume required. The display shows the
Volume level of the Upper section.
To decrease the volume, press the bottom [DECREASE
VOLUME] control.
If the Upper section is playing with the DUAL effect, the
[UPPER MIXER] controls adjust both voices at the same time.
Muting the sections
If you want to exclude a section (mute, or turn off), you can
use the MIXER control buttons.
Simply press both [INCREASE VOLUME] and [DECREASE
VOLUME] buttons at the same time to mute the section
required. For example, if you press both the top and bottom
buttons of the [UPPER MIXER], the display will show UPPER
OFF.
To restore the volume to normal, press both the [INCREASE]
and [DECREASE VOLUME] buttons again at the same time.
Instant Piano Voice
Regardless of the current situation, you can recall the Piano
Voice instantly by pressing the [PIANO] button.
Pressing this button returns the keyboard to NORMAL single
voice play with the PIANO voice active across the entire
keyboard.
Press the [PIANO] button again to return to the previously
selected situation.
The [PIANO] button always returns
you to a single piano voice playing
across the full keyboard. You may
use the PIANO button as a return to
start button whenever you wish to
have only one sound active
across all 61 keys.
MUTE SECTION
GK340 7
PITCH DOWN
PITCH UP
Add Pitch Bend to your playing
While you play, you can add Pitch Bend to your keyboard
sounds by using the [PITCH BEND] buttons located to the
left of the control panel. You can bend the pitch 2 semitones
above or below normal using these controls.
Hold down the top [PITCH BEND] button to bend the notes up.
Hold down the bottom [PITCH BEND] button to bend the
notes down.
The pitch returns to normal when you release the button.
Pitch Bend is aglide (or glissato) effect which simulates
the effect heard in certain instruments (trombone, guitar,
violin, etc.).
Play with Effects or bypass them
While you play, one or both effects (Reverb and/or Chorus)
will be shown active by the small black indicator arrow at the
top of the display. This means that the current Performance
is being processed by one or both effect types.
By means of the [REVERB] and [CHORUS] buttons on the
extreme right hand side of the control panel, you can turn
the effect on or off at will. When the small black display
arrow is shown pointing to the REVERB and/or CHORUS
indicator, the current voices are playing with
the effects. When one or both indicators are
off, the respective effect is bypassed and the
sounds play with no effect.
To restore the effect, press the same button
again.
8 Reverbs and 8 Chorus (Modulation effects) are available to
choose from and both effects units have an independent effect
level control. For further details refer to the section entitled
The Digital Effects on page 14.
Touch Response
The [TOUCH] button is a general function which
affects the keyboard globally. The GK340
keyboard is Velocity Sensitive; in other words,
the harder you play on the keys, the louder the
sound becomes, as occurs in an acoustic piano.
If you prefer to play on the keyboard without
TOUCH RESPONSE, you can disable the function by pressing
the [TOUCH] button.
The small black arrow pointing to the Touch indicator will
turn off.
Press the [TOUCH] button again to restore TOUCH RESPONSE
to the keyboard.

The Octave  transposer
Whether you are playing with Styles or just Voices in single,
dual or split mode, you can octave-shift the current Voice
down one octave (maximum) in real time. The current Voice
is shown in the display by the message VOICE 1, VOICE 2 or
LOWER (when the [SPLIT/LOWER] button is held down).
1. Press the [OCTAVE] button.
A small black display arrow points to the OCTAVE  function
on the right to show that the current voice is set to play
one octave lower than normal. In the example, Voice 1 is
shown set to play an octave lower.
Cancelling the Octave Transpose setting
2. To cancel the octave transposition, press the [OCTAVE
and +] button again. The small black OCTAVE  display
indicator turns off.
Styles - Auto-Accompaniment
What are the Styles?
Styles are a collection of musical patterns representing many
types of music, ranging from rock and pop to traditional and
ethnic music. The GK340 contains 96 different auto-
accompaniment Styles that can be used to provide fully-
orchestrated arrangements. The sophisticated Auto Accom-
paniment system can provide automated bass and chord
backing that is perfectly matched to the selected accompa-
niment Style. The Styles a formed by 5 sections, or tracks,
that generate the automatic arrangements: Drums, Bass and
3 Accomp, and an additional two tracks, Upper and Lower,
for the keyboard sounds. The automatic arrangements are
triggered by playing chords (fingered or one-finger) on the
lower part of the keyboard below the split point.
Selecting Style Mode
To select the Styles, you must set the GK340 to STYLE mode.
1. Press the [STYLE] button.
At the center of the display, the message STYLE is shown
to show that the instrument is ready to accept a STYLE
selection.
To enable the Style auto-accompaniments, you must select
one of the two chord recognition modes (ONE FINGER or
FINGERED).
2. Press the [SINGLE TOUCH PLAY] button.
Pressing this button activates the KEY START function
automatically and enables the Style auto-accompaniments
by recalling one of the two chord recognition modes (ONE
FINGER or FINGERED). The left display arrowhead points
to FINGERED or ONE FINGER. The display example shows
FINGERED selected.
The FINGERED and ONE FINGER chord recognition modes
are explained in detail further ahead.
Note: When SINGLE TOUCH PLAY is
on, the sounds memorized in the Style
Performance are assigned to all the
tracks. Selecting a Style changes the
sounds of the accompaniment sections
(Drums, Bass, Accomp) as well as the
keyboard sections (Upper 1, Upper 2,
Lower). When SINGLE TOUCH PLAY
is off, selecting a Style changes the
sounds of the accompaniment sections
only.
GK340 9

Use the numeric keypad to select a Style
Using the numeric keypad is the quickest way to go directly
to the Style you need, but first, you must know the exact
number of the Style. The name and corresponding number
of all the Styles in memory are silkscreened above the display
on the left. Youll see that they are organized in Groups (8
BEAT, 16 BEAT, ROCK, etc.) and numbered from 01 through
to 96. Select the Style you want by entering the corresponding
two digits in sequence.
5. For example, to select Style number 17 (Shuffle 2), press
button [1] then [7].
Selecting the Styles by recalling the Memory
Another quick way of selecting the Styles is by selecting the
Performances, but this means that you have to remember
which Style is memorized in the Memoriy.
If you use the Performances to select Styles, remember to
turn off the S.T. PLAY button. You can also memorize your
preferred Styles to these buttons with Write Memory. This
argument is explained in detail further ahead on page 16.
Playing the Styles
6. Once you have selected a Style, press the [START/STOP] button.
Youll hear the Drums accompaniment track start to play.
7. Play a note or chord on the left part of the keyboard below
note F#3 to trigger the automatic accompaniments.
An automatic accompaniment will start to play, generated
by the Style sections: Drums, Bass and Accomp. As you change
chord from Major to minor or seventh, etc., you will notice a
change of style pattern. Each time you change key, for example,
from C to F, the Style pattern will transpose automatically.
The names of the recognized chords are displayed in the left hand
corner of the display. For example, if you play the chord of C, the
display will show the large letter C. If you play a chord not
recognized by the instruments chord recognition system, the
current pattern will not change until you play a recognized chord.
Also shown in the display are 4 round Beat pattern indicators
which show the current beat of the bar as you play your style.
The first bar of every two-bar cycle shows all 4 indicators,
while every other beat shown one small indicator. The first
beat of the second bar is shown with the larger beat indicator.
To play your Style using the automatic functions (Var, Key
Start, Intro, Fill, Ending), see the section entitled Using
the Style Auto functions further ahead.
8. Press the [START/STOP] button if you want to stop the Style.
You can select a Style in three different ways:
Use the [-] and [+] buttons to select a Style
In STYLE mode, the [] and [+] buttons of the numeric
keypad step through the individual Styles one by one.
3. Press the [+] button to select the Styles in increasing
numerical order.
4. Press the [] button to select the Styles in reverse order.
Holding the button down scrolls rapidly forwards or backwards
through all the Styles. The selected Style number is shown
at the center of the display.
NOTE: If you hear a Drum pattern only
without automatic accompaniment
when you play a note or chord on the
Lower keyboard, check that you are
not in NORMAL or SPLIT mode. The
arrowhead must point to either
FINGERED or ONE FINGER for the
Style accompaniment to play.

To restore the Styles memorized Tempo, press both the
[TEMPO/+] buttons at the same time.
About the Chord Recognition Modes
The GK340 allows you to choose between two different Chord
recognition modes: FINGERED and ONE FINGER. The chords
that you play (Fingered or One Finger type) must be played
on the lower part of the keyboard dedicated to the Auto Bass
Chords (from note C2 up to and including note F#3).
FINGERED mode requires that you press at least 3 notes
for a chord to be recognized.
ONE FINGER mode requires that you press only one note
for a Major chord to be recognized. Other chords require
more notes.
1. If a Chord recognition mode isnt selected, press the
[MODE] button as many times as necessary until the left
display arrowhead points to either FINGERED or ONE FIN-
GER.
2. Press the [START/STOP] button to start the current Style.
3. If you select FINGERED, play a chord of at least 3 notes
on the Auto Bass Chord section of the keyboard to trigger
the auto-accompaniments.
If you select ONE FINGER, play one note on the Auto Bass
Chord section of the keyboard to trigger the Major chord
of the auto-accompaniments Other chords using the One
finger method involves the use of two or three fingers.
In the Appendix youll find useful reference charts for Fin-
gered and One Finger chords:
FINGERED (Appendix A);
ONE FINGER (Appendix B).
Note: If you change Style while the
rhythms are playing, the current Tem-
po rests unchanged. The memorized
Style Tempo is recalled only when the
Style is not playing.
GK340 11
Using the Style Auto functions
The Styles provide a wide variety of automatic functions that
make the GK340 very easy to play. The functions are found
in the ACCOMPANIMENT CONTROL section.
Select the Fill In and change Style Variation
Each Style has two accompaniment patterns, NORMAL and
VARIATION, which you can select at any time before or
after starting to play the Styles by pressing the corresponding
button. The status of the LED on the FILL 1 or FILL 2
buttons tells you which Style pattern is active for play, Normal
or Variation.
When you press the [FILL 1/NORMAL] or the [FILL 2/
VAR] button during playback, the current pattern will be

ceed with the same pattern or variation, depending on which
button you press.
The LED of the button pressed will turn on while the LED of
the other button will turn off.
Start the Style accompaniments with Key Start
The KEY START function allows you to synchronize the start
of your Style with a note or chord pressed on the keyboard
without using the Start/Stop button.
When you press the [KEY START] button, the display shows
4 flashing black dots (beat pattern indicators) after the word
TEMPO to indicate the synchro start stand-by. Now, if you
play a note or chord on the lower part of the keyboard, the
Style pattern starts automatically.
Start the Style with an Intro pattern
Before starting the Style, press the [INTRO] button to put
the instrument into intro-stand-by mode. The LED of the

Balancing the Style accompaniment tracks with the Mixer
When playing with Styles, you can adjust the volume of one
section with respect to the others using the [MIXER] Volu-
me controls. You will be able to balance all the Style sections;
Drums, Bass, Accomp as well as the Lower and Upper
keyboard sections. How the MIXER controls are organized is
explained on page 6.
In Style mode, to increase the volume of the Bass track, for
example, press the top [INCREASE VOLUME] button and
hold it down until you reach the Volume required.
The display shows the Volume level of the section being
controlled, in this case the Bass section.
To decrease the volume, press the bottom [DECREASE VO-
LUME] control.
MUTE TRACKS
Muting the Style tracks
If you want to exclude a section (mute, or turn off), simply
press both [INCREASE VOLUME] and [DECREASE VOLU-
ME] buttons at the same time to mute the section required.
For example, to play your Upper and Lower voices with the
BASS accompaniment only, mute the DRUMS and ACCOMP
tracks. The display will show OFF for the respective section.
To restore the volume to normal, press both the [INCREASE]
and [DECREASE VOLUME] buttons again at the same time.
Using the Single Touch Play settings in
Style mode
The SINGLE TOUCH PLAY settings are a quick and easy way
of reconfiguring the voices of the UPPER and LOWER sections
of a Style by pressing only one button while you are playing,
without having to stop to change voices manually.
When you play the Styles with the [SINGLE TOUCH PLAY]
button on, each Style you select recalls a panel configuration
(voices and volume settings) for the accompaniment sec-
tions (Drums, Bass, Accomp) as well as for the Upper and
Lower sections.
The S.T. PLAY settings are recalled using the first four but-
tons of the MEMORY section [M1 - M4].
The GK340 provides a total of 96 x 4 = 384 different panel
configurations for each Style.
GK340 13
Selecting the S.T. Play settings
1. Select a Style using the methods already described.
2. Press the [S.T. PLAY] button. The display will show a
small black arrowhead pointing to the S.T.PLAY indicator
in the bottom left hand corner.
Make sure that one of the two chord recognition modes is
selected.
3. Start the Style using the methods already described (Key
Start, Intro, etc.).
4. While you are playing the Style, press one of the SINGLE
TOUCH PLAY buttons ([M1], [M2], [M3] or [M4]). The
display will show the current Single Touch Play setting.
Youll hear a change of voice configuration and the Style
Variation may also change.
5. Repeat the selection procedure of the SINGLE TOUCH PLAY
settings after changing other Styles.
On the following page there are instructions on how to
store your preferred settings into the 6 memories.
Changing the accompaniment Split Point
If you want to increase or decrease the keyboard area
dedicated to the Style chords, you can change the Split Point
setting to any note of the keyboard and memorize the setting
to a Performance. The factory setting corresponds to note
F#3.
1. Press and hold the [MODE] button.
The display will show the current Split Point setting
expressed as a note of the keyboard, together with the
number of the Voice assigned to the LOWER section. In
this example, the current Split Point is shown as note F#3.
(If you release the [MODE] button, the display will return
to the previous situation.
2. While still holding down the [MODE] button, press a key
corresponding to the new Split point.
(If you use the [+]/[] buttons in this situation, you will
change the voice of the Lower section).
The new Split Point corresponding to the key you press
will be shown in the display. For example, if you press
note C4, the display will show the letter C on the extreme
left and the number 4 at the center.
3. Release the [MODE] button to return to the previous
display.
The new Split Point can be memorized to a Memory using
the write memory procedure, explained on the following
page.
Note: When the [S.T. PLAY] button
is on (display indicator on), the two
MEMORY buttons [M5] and [M6] are
disabled for Performance selection.
Note: The S.T. PLAY settings change the
configuration of the UPPER and LOWER
sections only.
Note: The Split Point can be different
for each Performance, and the settings
remain memorized even after turning
the instrument off.

Digital Effects
The GK340 contains a Digital multi-effects processor which
adds realism to your playing.
The Digital Signal Processor (DSP) consists of one unit which
process the Performances with Reverb and Chorus effects.
The buttons which control the Digital Effect are DSP button.
The DSP indicators
When the DSP display indicators are on, all the voices of the
current Performance will play with their programmed effects.
When one or both the corresponding display indicators are
off, the sounds will play dry (without effects).
The Memory buttons and Store Memory
You have seen that the Single Touch Play settings recall factory-set
configurations for the current Style when the [S.T. PLAY] button is on.
You have also seen that, when S.T.PLAY is off, (display
indicator off), the 6 buttons of the PERFORMANCE section
recall factory-set panel configurations (see page 5), includ-
ing Voices, Volumes, Style, Variation, Split Point, etc..
How to Store a Memory
If you dont want to use the factory Performance settings, you can
memorize your own panel configurations to the PERFORMANCE
buttons. This very useful feature allows you to store up to 6 pre-
ferred panel configurations, including Style, Variation and other se-
lections, which you can then recall at the touch of a single button.
To memorize a Performance, the first thing to do is to modify one of
the factory set situations. For example, if you select STYLE number
45 (Swing) with Single Touch Play on, the voices recalled for the
Upper and Lower sections will be Organ 2 and Strings respectively.
You only need to change one aspect of any factory setting to
be able to save the new setting as a new Performance. In our
example, lets change the voice assigned to the Voice 1 section.
1. Press the [VOICE/SONG/STYLE] button, press the
[S.T.PLAY] button, then select Style n. 45 (Swing).
2. Press the [VOICE/SONG/STYLE] button and select a
different Voice by using either the [+] and [] buttons, or
the numeric keypad (voice 27, Jazz Guitar, for this example).
3. Deactivate the Single Touch Play function (press the
[S.T.PLAY]).
4. Hold down the [STORE] button and simultaneously press
one of the PERFORMANCE buttons [M1] - [M6]. For
example, if you press [M5]:
The small black arrowhead at the bottom of the display
will show the current Performance.
Whatever information was previously stored in the selected
button will be erased by the new data.
5. At this point, you can check if your new Performance has
been stored. Changing the panel situation (for example,
select a Voice or Style), then press the MEMORY button that
you used to store your Performance in point 4 above.
GK340 15
The Sequencer
Your GK340 contains a very simple and easy to use
sequencer which records whatever you play and plays
back the recorded sequence just as you played it. You
can record in Voice mode or Style mode with one or two
melody tracks. In playback, you can play along with the
recorded sequence using different voices to those used in
the Melody tracks. The following example explains how
to record a sequence using the Accompaniments.
1. Set the instrument for Style play and select a Style.
(Follow the instructions explained on page 9).
2. Press the [REC] button.
(the four Beat indicators in the display will flash).
3. If you want to start the recording of the Style with an
introduction, press the [INTRO] button to preset the Intro.
4. Start to record the notes you play.
The Key Start function triggers the Style accompaniment
patterns when you play a chord on the keyboard below
the split point. If you play a note or chord on the upper
part of the keyboard, only the drum track will be triggered.
5. While playing, use the Fills, change the Variation, change
Voices for the Upper and Lower sections, activate/
deactivate Dual mode, etc.. Whatever you do will be
captured by the sequencer.
6. Stop the recording with the [REC] button.
You can also stop the recording with an ending by press
the [ENDING] button.
Listen to the playback of a recorded Song
7. Press the [PLAY] button to listen to the playback of your
recording.
While the recorded sequence is playing, you can play along
using any voice. Simply select the one you want and play.
Record a new song
To record a new Song and overwrite the old one, simply press
the [REC] button and the buttons you want to record.
Proceed to record your new song using the method already
described. The old song will be overwritten (cancelled).
If you press [PLAY] when the sequencer contains no recorded
notes, the display will show an EMPTY message.
